Application Scenarios
Use C9350-NM-4C when a supported C9350-48HX or C9350-48TX switch needs four 40G or 100G uplinks for high-bandwidth aggregation.
Choose this module when a C9350-48HX deployment needs high-speed uplinks to match dense mGig access demand from Wi-Fi, workstations, or campus aggregation.
C9350-NM-4C is also relevant for C9350-48TX projects where the access layer uses 10G copper ports and the uplink design needs more than two QSFP28 ports.

- Choose C9350-NM-4C when the switch is C9350-48HX or C9350-48TX and the design needs four QSFP28 uplinks.
- Choose C9350-NM-2C when two 40G/100G uplinks are enough or the installed C9350 model is not listed for C9350-NM-4C.
- Choose C9350-NM-8Y when the uplink plan uses SFP-family 1G/10G/25G/50G optics instead of QSFP links.
Selection Guide
1. Choose C9350-NM-4C only for listed switch models
Select this module for C9350-48HX or C9350-48TX deployments that require four 40G or 100G QSFP28 uplinks.
2. Choose C9350-NM-2C for broader C9350 compatibility
If the installed switch is C9350-48U, C9350-48P, C9350-48T, or another C9350 model not listed for C9350-NM-4C, compare C9350-NM-2C instead.
3. Choose C9350-NM-8Y for SFP uplink media
If the network uses 10G/25G/50G SFP-family uplinks, C9350-NM-8Y is usually the correct module type.
4. Verify optics, switch model, and port count before ordering
Before purchase, confirm the switch SKU, the required number of QSFP links, supported optics or cables, and whether the design needs breakout support.

|
Port Count |
Four QSFP28 uplinks |
Determines whether C9350-NM-4C is necessary or C9350-NM-2C is enough |
|
Optics or Cables |
Cisco-supported QSFP optics, DACs, AOCs, or breakout cables |

|
Software Baseline |
Cisco IOS XE release for the target switch |
Helps avoid module recognition or support issues |
|
Alternative Module |
C9350-NM-2C or C9350-NM-8Y |
